Abstract
This study examined effects of binocular information on visual orientation perception and visuomotor control of a hand using two tasks in which observers matched the orientation of two rods. On the perceptual matching task, they were asked to make a visual judgment of the orientation of two rods. On the motor (preshaping) task, they were asked to move a rod which they can not see by their hands so as to match the orientation of the presented rod. Decrement in availability of binocular cues produced considerable disruptions on the motor task, while did less disruptions on the perceptual matching task. Hence binocular information seemed to play a critical role on the motor task. These results are consistent with recent suggestions that visual perception and visually guided motor control should be mediated by separate visual pathways.
